AUTOMATIC CAR-BRAKE.

Specification of Letters Patent.

Patented July 11, 19111.

Application filed September 22, 1910. Serial No. 583,323.

To all whom it may concern:

Be it known that I, TRACY S. HAUSER, a citizen of the United States,residing at Northup, in the county of Gallia and State of Ohio, haveinvented certain new and useful Improvements in Automatic Car-Brakes, ofwhich the following is a specification.

This invention relates to cars, and particularly to car brakes whichwill automatically be applied when the force exerted on the draw bar isremoved.

It also contemplates the construction of a device of this nature whichwill automatically remove the brakes whenever a push or a pull isexerted on said draw bar.

With the above and other objects in view, this invention consists in theconstruction, combination, and arrangement of parts, all as hereinaftermore fully described, claimed, and illustrated in the accompanyingdrawings, wherein Figure 1 is a top plan View of a car frameillustrating the mechanism forming the subject matter of the presentinvention in the positions taken by the elements when a pull is exertedon the draw bar, dotted lines in dicating the positions taken by thecomponent parts when the brake is automatically applied; Fig. 2 is asimilar view illustrating the positions of the elements of the presentinvention when a push is exerted on the draw bar.

Referring more particularly to the drawings, 10 indicates a car frame ofthe usual construction having the axles 11 mounted therein which carryat their terminals the wheels 12. A brake beam 13 cooperates with eachset of said wheels 12 and is provided at its terminals with the brakeshoes 14 which are adapted to operate against said wheels. In eachterminal of the frame 10 is a draw bar 15 reciprocatingly mounted whichextends inwardly to and beyond the adjacent brake beam 18, said draw barbeing provided with the draw head 16 of the usual standard construction.A sleeve 17 is slidably mounted on each draw bar 15, each upon applyinga push to said draw bar, as

will be hereinafter more fully and specifically described.

A lever 20 is pivoted adjacent to each terminal of each brake beam 13, aportion of said lever extending on either side of the brake beam. Theterminal of the levers 20 adjacent to the terminals of the car frame 10are connected to the strong coiled springs 21 which are in turnconnected to the end pieces of the car frame. The opposite terminals ofthe levers 20 are connected to the levers 22, said connections beingspaced from the outer terminals of said levers. The inner terminals ofthe levers 22 are connected to the draw bars 15 by the chains 23, thuswhen the draw bars 15 are moved the levers 22 will likewise move. Inorder to provide a stationary pivotal pointfor the levers 22, a link 24:is interposed between each adjacent pair of the levers 22 on the sameside of the car, the length of this link being constant the levers willremain stationary with respect to longitudinal movement. This connectionwill provide a pivotal point or fulcrum for the levers 22. The outerterminal of each lever 22 is connected to the adjacent arm of the sleeve18 by the link 25. From this construction it will be understood thatupon any movement of said sleeve, the levers 22 mustalso move. Thecorresponding levers 22 located on the same side of the car areconnected by the crossed links 26 which cause the levers to operatesimultaneously, but in opposite directions.

From the foregoing it will be understood that when a pull is exerted onone of the draw bars 15, the inner terminals of the levers will moveabout the pivotal point or fulcrum formed by the links 2a. This movementwill cause a pull to be exerted on the levers 20 carried by the brakebeam, thereby removing the shoes 14: from engagement with the wheels 12.The opposite sets of levers 22 are operated in a similar direction bythe connecting crossed links 26, thereby insuring the release of bothsets of wheels. \Vhen a push is exerted on the draw bars, the flange 19comes into contact with the sleeve 17, thereby exerting a push upon thelevers or links 25 causing the inner terminals of the levers 22 to swingoutwardly about the pivotal point formed by the links 24, again removingthe brake shoes from contact with the wheels through the instrumentalityof the levers 20. The crossed links 26 cause the reverse movement of thecorresponding levers on the opposite end of the car. \Vhenever a push orpull is being exerted on the draw bars, the brake shoes are brought intocontact with the wheels by the tension of the springs 21. Should it bedesired to release the brake by hand, a chain 27 is connected to thechains 23 and operates around a brake shaft 28.

Having thus fully described my invention, what is claimed as new is 1.The combination with a car frame, of wheels carried thereby, brake beamscarrying brake shoes cooperating with said wheels, draw bars operatingin the ends of said frame, levers pivotally carried by said brake beamsand extending on both sides thereof, levers pivotally connected to saidlast named levers, and having a connection between their inner terminalsand the inner terminals of said draw bars, means interposed between theouter terminals of the levers carried by the brake beams and the endpieces of said car to normally cause said brake shoes to engage saidwheels, and means whereby a. pull or push on the draw bars will releasesaid shoes.

2. The combination with a car frame, of wheels carried thereby, brakebeams carrying brake shoes cooperating with said wheels, draw barsoperating in the ends of said frame, levers pivotally carried by saidbrake beams and extending on both sides thereof, levers pivotallyconnected to said last named levers, and having a connection betweentheir inner terminals and the inner terminals of said draw bars, meansinterposed between the outer terminals of the levers carried by thebrake beams and the end pieces of said car to normally cause said brakeshoes to engage said wheels, a connection between the correspondinglevers at opposite ends of the car, and means whereby said correspondinglevers may be operated oppositely to disengage said brake beams from thewheels.

3. The combination with a car frame, of

wheels carried thereby, brake beams carrying brake shoes cooperatingwith said wheels, draw bars operating in the ends of said frame, leverspivotally carried by said brake beams and. extending on both sidesthereof, levers pivotally connected to said last named levers, andhaving a connection between their inner terminals and the innerterminals of. said draw bars, means interposed between the outerterminals of the levers carried by the brake beams and the end pieces ofsaid car to normally cause said brake shoes to engage said wheels, aconnection between the corresponding levers at opposite ends of the car,and crossed links connecting the corresponding levers at the oppositeends of the car for causing the same to operate in oppodraw barsoperating in the ends of said frame, levers pivotally carried by saidbrake beams and extending on both sides thereof, levers pivotallyconnected to said last named levers, and having a connection betweentheir inner terminals and the inner terminals of said draw bars, meansinterposed between the outer terminals of the levers carried by thebrake beams and the end pieces of said car to normally cause said brakeshoes to engage said wheels, a connection between the correspondinglevers at opposite ends of the car, crossed links connecting thecorresponding levers at the opposite ends of the car for causing thesame to operate in opposite directions to disengage said brake shoesfrom the wheels aforesaid.

5. The combination with a car frame, of wheels carried thereby, brakebeams carrying the brake shoes cooperating with said wheels, draw barsreciprocatingly mounted in the opposite ends of said car extending toand beyond said brake beams, a lever and link connection between saiddraw bars and adjacent to the brake beams, springs connected to saidlever and link connect-ion whereby the brake shoes normally engage thewheels, a sleeve mounted on said draw bars, and means whereby saidsleeve may operate said lever and link connection upon the inwardmovement of the drawbar.

6. The combination with a car frame, of

wheels carried thereby, brake beams carrying the brake shoes cooperatingwith said wheels, draw bars reciprocatingly mounted in the opposite endsof said car extending to and beyond said brake beams, a lever and linkconnect-ion between said draw bars and adjacent to the brake beams,springs connected to said lever and link connection whereby the brakeshoes normally engage the wheels, a sleeve mounted on said draw bars, alink connection between said sleeves and said lever and link connection,a flange carried by each draw bar adapted to co.- operate with thecorresponding sleeve causing said lever and link connection to operateupon the inward movement of the drawbar, and means whereby thecorresponding mechanisms at the opposite ends of the car may operate inopposite direct-ions.

In testimony whereof I affix my signature in presence of two witnesses.
